Qtimer Cannot Be Stopped From Another Thread


And the object itself lives in the context of the thread that created it (the object, not the thread) therefore it lives in context of the main thread. I need adding a timer to my program.

I didn't mind so much when it was just messages, but today it is causing the calibre process to crash and close. Exemplary. QTimer *main_t3rdMode, *main_connectTimer, main_vkTimer; QTimer scenarioTimer; private slots: . . . Why "silver-tongued" for someone who is convincing?

Does the thread do anything else besides running the timer? But I can't use it directly or maybe you can tell me how... –Matt Oct 20 '14 at 10:48 Why you can't use it directly? this was after a clean start of calibre-debug -g with not starting any of my plugins My normal view lately has been with the tag browser, cover browser and book details

You can either create, start stop in the same thread or use signal and slots to trigger start and stop operations for timers. Provided that the timer doesn't have a parent it has to be you or the timer is not deleted at all. Any ideas what may be happening?

I even suggest you change your run() a bit: void ...:run(){ QTimer timer; connect(&timer, SIGNAL(timeout()), this, SLOT(checkTimestamp())); timer.start(5000); exec(); // the timer will get deleted when run() returns } By the http://www.qtforum.org/article/34178/timers-and-threads.html Would it be better to handle the deletion of m_pTimer in response to the QThread::finished() signal?

One is a private member in a QThread (where I believe the warnings are coming from). Move the contents of your destructor into the run() method right after exec(). Since you say you are new to Qt, I suggest you go through some tutorials before proceeding so that you will know what Qt has to offer and don't end up If it contains any objects that have been waiting to be initialized for too long, they are rescheduled and removed from the list.

Do I have to use additional threads (QThread) to the main thread? but I'm starting it from the new thread!

A story behind a weird inductor My cat sat on my laptop, now the right side of my keyboard types the wrong characters Is it possible for an diesel engine computer The fact that you are seeing the messages while calibre is running is different from what I see. The end result, of course, is a crash in QTimer because the value is bad. The other is a private member of my QMainWindow, but the way I'm using the app, the timer shouldn't be created (it should only be created when running the app from
